Objective The chemical constituents of Suxiao Jiuxin Pills (SJP) were studied by ultra-high-performance liquid chromatography coupled with quadruple time of flight mass spectrometry (UPLC-Q-TOF-MS). Methods Agilent Poroshell 120 EC C₁₈ column (150 mm × 3.0 mm, 2.7 μm) was used for gradient elution with 0.1% formic acid aqueous solution and acetonitrile as mobile phases. The volume flow rate was 0.8 mL·min^-1 (split ratio 1: 2). Dual AJS ESI source was used to collect data in positive and negative ion modes. A compound library was established. According to the precise relative molecular weight and secondary fragment ion information of compounds, the main chemical constituents of SJP were identified with reference data. Results 90 constituents were identified from SJP, including 47 phthalides, 11 organic acids, 13 alkaloids, four terpenoids and 15 other compounds. Conclusion The method is rapid, accurate and convenient, which provides scientific data support and method reference for elucidating the pharmacodynamic substance basis of SJP and further studying its metabolism process in vivo.
